One of the lightest and most efficient pedals on the planet, just got lighter and more efficient. The PD-9100 is 14 grams lighter than its PD-9000 predecessor. To get to the 234-gram weight we looked at every detail from the injection–molded carbon-composite body, to the hollow cleat bolts. The new PD-9100 is the perfect balance of strength-to-weight rigidity and efficiency. It’s the ultimate expression of the SPD-SL platform.
